DESCRIPTION OF THE PRIOR ART

Hurd reported first the direct synthesis of allyldichlorosilane from allyl chloride and metallic silicon in 1945 (D. T. Hurd, J. Am. Chem. Soc., 87, 1813 (1945)). When allyl chloride was reacted with a 9:1 Si--Cu alloy, a vigorous exothermic reaction occurred even at 250° C. The condensates obtained contained trichlorosilane, tetrachlorosilane, allyldichlorosilane, diallyldichlorosilane, and allyltrichlorosilane predominates due to the decomposition of allyl chloride during the reaction. However, this reaction has never been used on a large scale in industry, because of the decomposition of allyl chloride and the easy polymerization of diallyldichlorosilane at high temperature above 130° C.

Mironov and Zelinskii reported later that they obtained only 644 g of a mixture of allylchlorosilanes from the reaction of a 5:1 Si--Cu alloy with 2 kg of allyl chloride at 300° C. The product mixture contained 356 g of allyldichlorosilane, 185 g of allyltrichlorosilane, and 103 g of diallydichlorosilane (V. M. Mironov and D. N. Zelinskii, Isvest. Akad. Nauk S.S.S.R,. Otdel. Khim. Nauk, 383 (1957)). The production of allyldichlorosilane and allyltrichloro-silane indicates that allyl chloride decomposed under the reaction conditions and dehydrochlorination or dechlorination were accompanied. This is why the yield was under 30%, indicating that the process was not economically feasible. ##STR9##

We reported a preparation method of allylchlorosilanes by directly reacting silicon metal simultaneously with allyl chloride and hydrogen chloride in the presence of copper catalyst at a temperature from 220°0 C. to 350° C. Allyldichlorosilane was obtained as the major product indicating one mole of each reactant reacted with the same silicon atom. When sufficient hydrogen chloride was added, diallyldichlorosilane was not Formed. This eliminated the polymerization problem involved in the direct synthesis (Korean Patent application 92-10292 (92. 6. 13)). ##STR10##

Nametkin and his co-workers reported that the Friedel-Crafts type addition of allylchlorosilanes to mono substituted benzenes in order to give 3-phenyl-1-silabutane (N. S. Namerkin, V. M. Vdovin, E. S. Finkelshtein, V.D. Oppengeium, and N. A. Chekalina, Izv. Akad. Nauk SSSR, Set. Khim. , 1966 (11) , 1998-2004). They reacted allyltrichlorosilane, allyldichlorosilane, allylmethyldichlorosilane, or allyltrimethylsilane with benzene, chlorobenzene, bromobenzene, or benzyltrichlorosilane in the presence of aluminum chloride to give 2-phenylpropylsilanes. The yield of 2-(phenyl)propyldichlorosilane from the reaction of allyldichlorosilane with benzene was 60%. ##STR11##

The present inventors reported the preparation method of (2-arylpropyl)dichlorosilane represented by the formula (I) by the Frieden-Crafts alkylation of various substituted aromatic compounds with allyldichlorosilane in the presence of Lewis acid catalysts (Korean Patent application 92-12996 (92. 7. 21)). ##STR12##

The present inventors also reported a process for preparing new organochlorosilanes by the hydrosilation reaction of Si--H bond containing bissilylalkanes with olefin compounds in the presence of catalysts such as chloroplatinic acid, platinum on silica, tributylamine and Pd, Rh, Ni metals (Korean Patent application 92-12998 (92. 7.21)).

SUMMARY OF THE INVENTION

The present invention relates to (2-arylpropyl) alkylsilanes represented by the formula III and a process for the preparation of the compounds of formula III comprising reacting (2-arylpropyl)silanes represented by the formula I with olefin compounds represented by the formula II in the presence of hydrosilation catalysts such as chloroplatanic acid, platinum on silica, tributylamine and Pd, Rh, Ni metals. ##STR13##

In the formulas (I) and (III), R¹ and R² represent independently hydrogen, alkyl(C₁ -C₄), fluoro, chloro or bromo; and Ar represents phenyl ring, naphthalene ring or biphenyl ring. X represents hydrogen or chloro group. In the formula (III), R represents --(CH₂ CH₂)--R³, sec-butyl, or cyclohexyl wherein R³ is Ph, CH₂ Cl, C_(n) H_(2n) CH₃ (n=0-15), CH₂ Si(Me)_(m) Cl_(3-m) (m=0-3), (CH₂)₂ Si(Me),(OMe)_(3-m) (m=0-3), (CH₂)₃ Si(Me)_(m) (OMe)_(3-m) (m=0-3), Si(Me)_(m) Cl_(3-m) (m=0-3), CF₃, CN, CH₂ CN, ##STR15## CH═CH₂, (CH₂)₄ CH═CH₂, ##STR16## or Ph-CH₂ Cl.

The (2-arylpropyl)alkyldichlorosilane producing hydrosilation reactions of the present invention can be run in standard laboratory glasswares or commercial equipments, under inert atmosphere, with units for external heating and cooling, stirring, and for incremental addition of the start-silanes or olefins. The reaction can be carried out in most of organic solvents, but is also proceeds in neat condition. When allyl chloride is hydrosilated, the reactor should be pressurized because propylene gas is evolved as a by-product.

In a typical preparation, (2-arylpropyl)dichlorosilane and the hydrosilation catalyst are placed in the reactor under inert atmosphere. The olefin compound is then slowly added to the solution with stirring. The reactions may be sufficiently exothermic at controlled addition rates to maintain to reflux without continuously carrying out external heating. After completion of addition, heating may be carried out for a certain period of time to complete the hydrosilation and then the products may be fractionally distilled at atmosphere or under vacuum.

The invention will be further illustrated by the following examples. It is, however, not intended that this invention will be limited by the examples.

The reactor was refluxed for 3 hours. Vacuum distillation of the reaction products gave 9.4 g (bp, 131°-3° C./0.6 mmHg) of 4,4-dimethoxy-2-(2,5-dimethylphenyl)-4-siladecane.

EXAMPLE 16

In the same apparatus and procedures as EXAMPLE 1, 10.0 g (0.046 mole) of 3-phenyl-1,1-dimethoxy-1-silabutane, 3.7 g (0.07 mole) of acrylonitrile, and 0.3 g of nickel metal obtained from the reduction of nickel iodide with metallic sodium were placed under the dry nitrogen atmosphere. The reactor was refluxed for 3 hours. Vacuum distillation of the reaction products gave 9.0 g (bp, 120°-2° C./0.6 mmHg) of 1-cyano-3,3-dimethoxy-5-phenyl-3-silahexane.
